Hi DeGa,
thats the code iam using:
<code>
public void flv2jpg(String flv_filename,String jpg_filename, String
position) {
IConnection appConn = Red5.getConnectionLocal();
String str_userId = appConn.getClient().getId();
String str_path = "C:/Dokumente und Einstellungen/Admin/Eigene
Dateien/developement/workspace/0.6rc1/red5_server/webapps/streamactor/st
reams/";
log.info("#[flv2jpg CId:"+str_userId+"] triggered: ");
try {
Runtime runtime = Runtime.getRuntime();
Process proc = runtime.exec(new
String[]{str_path+"ffmpeg.exe","-i",str_path+flv_filename,
"-y","-f","singlejpeg","-ss",position,"-vframes","1","-an",
str_path+jpg_filename} );
// check for failure
} catch (Exception e) {
log.info(e);
}
}
<code/>
Its working for windows. Unfortunately you wont receive a return code
for windows-shell execution.
So, its a kind of blind executing.
Under linux you can use proc.exitValue(). successful execution returns
0. (but i havnt test it)
exitValue() with windows will wait eternaly.
Iam new to red5 and java. may be there is a better approach.
btw.: there are also java wrapper for the c libs of ffmpeg. Google "Java
wrapper for ffmpeg". With this you can use ffmpeg directly out of java.
but i havnt the muse to fight through.
have fun
